the fluid used for detection is filled through the fluid inlet 62, so that the resultant force direction at the end face sealing valve core 8 faces the pipeline inlet 61, when the fluid pressure is higher, the resultant force is higher, the end face sealing ring 81 and the pipeline are pressed more tightly, the sealing performance is better, and the self-sealing effect is achieved, and the first sealing ring 71 and the second sealing ring 72 also play a role in shaft side sealing.
The disassembly process of the pipeline and the pressing handle type pipeline quick joint comprises the following steps:
the pressing handle 11 is pressed downwards to drive the linkage valve core 12 to compress the valve core spring 5 until the linkage valve core 12 abuts against the adapter 65 to reach the lowest point of pressing downwards, in the pressing process, the clamping block spring 3 can be expanded to drive the clamping block group 2 to move, meanwhile, the valve core seat 4, the first sealing ring 71, the copper flat gasket 7 and the second sealing ring 72 are driven to move towards the fluid access port 62 together, the second sealing ring 72 always abuts against the two-side abutting protrusions 121 of the linkage valve core 12, in the moving process, the clamping block group 2 always keeps the outward expansion trend under the limiting effect of the valve core seat main body 41 of the valve core seat 4 and under the inclined plane effect of the inner side wall of the pipeline access port 61, and when the pressing handle 11 is pressed downwards, the clamping block group 2 is expanded to the level suitable for pulling out of the pipeline.
After the pipeline is disassembled, the pressing handle 11 is released, the valve core spring 5 gradually relaxes from the tightening state, the generated elastic force pushes the linkage valve core 12 to move towards the pipeline access port 61, the linkage valve core 12 drives the clamping block group 2, the valve core seat 4, the first sealing ring 71, the copper flat gasket 7 and the second sealing ring 72 to move towards the pipeline access port 61 together, the clamping block spring 3 is compressed to restore to the initial state, meanwhile, the end face sealing spring 9 restores to the relaxing state, and the end face sealing ring 81, the end face sealing valve core 8 and the third sealing ring 73 are pushed to restore to the initial position.
The following advantageous effects can be seen from the above embodiments:
the clamping block group can be forcedly separated in the assembling and disassembling processes of the pipeline, so that the clamping block group can be expanded to a level suitable for inserting and pulling out the pipeline, and the situations of pipeline jamming and joint damage are avoided; in the detection process, the pressure of the fluid can enable the resultant force direction of the end face sealing valve core and the linkage valve core to face the pipeline access port, the end face sealing ring is pressed with the pipeline more tightly, and the clamping force of the clamping block group on the pipeline is increased, so that the sealing performance of the joint and the stability of the pipeline are improved.
